Title: Tappet device of internal-combustion engine
Inventor: ICHIDA KATSUMI
IPC: F01L1/12
Filed: 1984-06-26
Abstract: PURPOSE:To minimize the relative sliding distance of a point of contact between a cam follower and a valve, so as to decrease the lateral load of the valve, by constituting the cam follower as it sways, according to the opening/closing of the valve, in almost equal angles centering around a position where the cam follower is right-angled with the axis of the valve. CONSTITUTION:A valve 7 and a cam shaft 10 are arranged as whose axes cross to each other at right angles, and a cam follower 12, one end of which is swayingly supported by an engine, is set between the valve 7 and the cam 10a. This follower 12 is constituted as it sways in almost equal angles (alpha beta) centering around the position of the follower 12, where a straight line L which passes through a point P of contact between the follower 12 and the valve 7 and a swaying center O of the follower 12, and an axis line Y of the valve 7, cross to each other at right angles, and consequently, the relative sliding width (s) of the said point P is minimized. In this way, the lateral load of the valve 7 can be decreased, and the following ability of the valve can be raised, partly because the reciprocating intertial mass of the cam follower is small.

Title: Collision buffering mechanism
Inventor: TAKAOKA DAIZO
IPC: G05D1/02
Filed: 1988-05-30
Abstract: PURPOSE:To evade the application of a large force to an obstacle by braking an unmanned traveling vehicle and at the same time releasing the fixture of a bumper means. CONSTITUTION:The buffering devices 10 hold fixedly a bumper 5 via the rods 9 so that the bumper 5 is kept front of the main body of an unmanned traveling vehicle 1 by a fixed distance while the vehicle 1 is normally traveling. While the state where the bumper 5 is fixed by the rods 9 is released when a signal showing a fact that the vehicle 1 collides against an obstacle is received from a control circuit 6. Thus the bumper 5 can freely move forth and back. In this case, the braking of the vehicle 1 is controlled so that the stopping distance of the vehicle 1 is kept within the distance L0 between the bumper 5 and the main body of the vehicle 1. As a result, the force of inertia of the vehicle 1 is never applied to the obstacle when the vehicle 1 collides against the obstacle. While the force of inertia of the bumper means only is applied to the obstacle.

Title: Forming method of resist pattern
Inventor: NISHIMURA EIJI
IPC: H01L21/30
Filed: 1984-06-27
Abstract: PURPOSE:To reduce a difference in X-Y dimensions of a resist pattern, to form the sectional shape of the resist pattern approximately vertically and to improve the accuracy of finishing of the pattern by excessively exposing a resist. CONSTITUTION:When a resist is exposed through scanning by a raster scanning system, the resist is given a dose of 1.5-2 times as mush as the optimum dose of electron beams. Consequently, the inclinations of beam distribution 12, 13 approach to steep beam distribution both in the X direction and the Y direction because high energy is obtained. A difference in inclinations in the Y direction changes at a value larger than a difference in the inclinations of beam distribution in the X direction. Accordingly, a difference (x1-y1) in X-Y dimensions is made smaller than that (X0-x0) in conventional devices, thus improving the accuracy of finishing of a pattern. Since the inclinations of beam distribution are made steep both in the X direction and the Y direction, the sectional profile of the resist pattern can be brought close to perpendicularity.

Title: Liquid crystal electrooptical device
Inventor: WATANABE TOSHIO
IPC: G02F1/1333
Filed: 1989-05-24
Abstract: PURPOSE:To facilitate the patterning of electrodes and to improve the yield of the process for production for the liquid crystal electrooptical device of a two layer type superposed with two liquid crystal cells by disposing the picture elements of one cell in the parts which are not the picture elements of the other cell. CONSTITUTION:The parts of the picture elements 3, 4 of the respective cells of the liquid crystal electrooptical device of the two layer type superposed with the 1st liquid crystal cell 1 and the 2nd liquid crystal cell 2 are disposed in the parts which are not the picture elements of the other cell. The light emitted from a light source 5 passes a polarizing plate 6 and becomes linearly polarized light when the picture element 3 is off at this time. This light is made into elliptically polarized light by passing the picture element 3 of the cell 1. The light is optically compensated by passing the cell 2 and arrives in the state of nearly the linearly polarized state at a polarizing plate 7. Since the picture elements 3 of the one cell 1 are disposed in the parts which are not the picture elements 4 of the other cell and, therefore, the spacing between the electrodes of one or both of the substrates of a pair of the substrates is widened. The patterning stage is consequently facilitated and the defects, such as shorting of the adjacent electrodes, are eliminated.
